The iFob program acts as a beacon, saying "I am here!" while listening for other iFob pings saying the same. Whenever one iFob finds another, the program lights up and automatically exchanges "micro profiles" with one another. Or, if you prefer to maintain your privacy and just lurk at the local bar, you can just set iFob to listen mode, and reach out to the other iFob users you may find as you choose.
